Application filed we 1',

tain new and useful Improvements in Manifold Coversyand I do herebydeclare the following to be a full clear, and exact de scription of theinvention, such as will en- 10 able others skilled in the art to whichit appertains to make and use the same. i

This invention relates to new and useful improvements in engineattachments and more particularly to an attachment adapted to be appliedto that type of engine used in automobiles, aeroplanes and the like, themain object of the present invention being the provision of a deviceadapted to be applied to the exhaust pipe and to partially enclose theexhaust pipe and extend over the intake manifold whereby to conduct theheat from the, exhaust pipe to the intake manifold whereby the fuelmixture passing into the engine cylinders through the intake 2 manifoldwill be thoroughly heated and the liquid particles vaporizedbeforereaching the cylinders.

Another object of this invention is the provision of a device which canbe quickly and readily applied to an engine without the necessity ofadditional bolts or other fastening means, the device being retained inposition by means of the bolts utilized to retain the well known form ofpipe clamps in position.

A further object of the present invention is the provision of a casingadapted to be arranged over a portion of the exhaust manifold and toenclose the intake manifold and having formed upon its interior aplurality of longitudinally and transversely extending ribs whereby theheat from theexhaust manifold will be readily conveyed downwardly to theintake manifold to thoroughly heat the fuel passing through the manifoldso that when the fuel reaches the engine cylinders it will be thoroughlyvaporized. A

With the above and other objects in View the invention consists in thenovel features of construction, combination and arrangement of partshereinafter more fully set forth, pointed out in the claim and shown inthe accompanying drawings in which Figure 1 is aside elevation of anauto- 1921. Serial No. 481,868.

mobile engine illustrating" my improved .device applied thereto Fig. 2is a longitudinal sectional'view' of my attachment, and.

"Fig. '3 is an interior perspective view.

Incarrying out my, invention Iprovide an elongated body member l'formedof metal and provided with 'OiitStandingcup shaped members 2 which areadapted to i I receive the usual pipe clamps used in securing the intakeandexhaust pipes, said clamps being retained in position by means of thebolts 3 and these bolts are utilized 1n securing my improved device inposition as each of the cup-shaped members 2 are provided with suitableopenings 4 to receive the bolts 3, the regular securing nuts being usedto clampthe device in position.

The body member 1 is provided at one end with an outstanding flange 5which extends along one side of the body to a point adjacent the centerthereof toflthus form a cup-shaped enclosure at the forward end of thebody. The opposite end of the body is provided with spaced flanges 6arranged uponcopposite sides of a recess 7, said recess being adapted toreceive one end of the pipe clamp which is not enclosed in the body ofthe attachment. i

Upon the interior of the body and formed upon opposite sides of thecenter or in other words upon opposite sides of the cup-shaped members2, are the spaced flanges 8 provided at intervals with suitable recesses9 arranged in transverse alignment whereby to receive the intake andexhaust pipes. The

ing a closure for the outer end of the device 7 whereby to. prevent theair from the fanreaching' the interior of the device and carryingthe'heated air to the rear of the engine. i

From theabove it will be noted-that 1 if have-provided a simple anddurable device which can be readily cast into a single piece so as toreduce the manufacture of the device to a minimum, making the samesimple veyed through the channel members to the in its construction sothat it can be placed upon the market and sold at a very low cost.

In applying the device, the nuts are removed from the bolts 3, thedevicearranged in position as shown in Fig. 1, the ends oi the bolts 3projecting through the openings 4 in the members 2, the nuts thenreplaced upon the bolts 3 and screwed down against the outer surfaces ofthe members 2. It Will= readily heated and vaporized before reaching theengine cylinders as the heat from.

the exhaust manifold Willbe readily conintake manifold. I claim: 5 j

In a device of the class described, a body member having cup-shapedrecesses formed therein and provided with perforations at thebottom'ofthe recesses, spaced flanges arranged upon opposite'sides ofthe center of the body, sa d flanges belng provided with transverserecesses, a plurality of transverse flanges arranged upon oppositesldesol the first flanges and a cup-shaped member ii'o'rm ed at one endof the body and,

and"

projecting parallel with the flanges as for the purpose set forth. Intestimony whereof I afli my signature.
